Helium has two neutrons and two protons in its nucleus.
the subatomic particles, protons and neutrons, form the nucleus.
Protons and neutrons.
proton, neutrons
These particles are neutrons and protons; they are formed from quarks and gluons.
Atomic nuclei have two kinds of subatomic particles, which are protons and neutrons.
nucleus....contains protons & neutrons
The nucleus of an atom contains only protons and neutrons. Electrons orbit the nucleus.
The three subatomic particles found in an atom are the Protons, Neutrons, and Electrons. But the subatomic particles found in the nucleus of an atom are the Protons, and Neutrons. The Electrons surround the nucleus and take up most of the volume.
Protons and neutrons are subatomic particles located in the atomic nucleus.
Atoms are made of a nucleus, which contains subatomic particles called neutrons and protons, and electrons, which orbit the nucleus in certain areas.
the subatomic particles, protons and neutrons, form the nucleus.
The centre of an atom is called the nucleus. The nucleus contains protons, which have a positive charge and neutrons which have no charge. Electrons are also subatomic particles but they go around the nucleus so they are not in the centre.
protons and neutrons
The three most commonly referred to subatomic particles are the proton, the neutron, and the electron. Protons and neutrons are the subatomic particles that reside in the atomic nucleus. Electrons, however, are located outside of the nucleus.
An atomic nucleus consists of protons and neutrons.
Neutrons and Protons
Protons and usually neutrons.
